Default slight surge at idle

when my foot is on the brake. It goes from 500-550 or 600 RPM, depending. It doesnt always do it, but it does happen a good amount of the time. It wont do it if I am in park or neutral, just when it is in D and my foot is on the brake...

any ideas?

I did really quick, but not very thoroughly at all though. I'll let it warm up tomorrow and check. Now the fact that it is happening when my foot is ON the brake leads me to think that if there's a vacuum leak, it's be from the brake booster, so thats what i will check first.

As far as my car, click the car in my sig and it takes you to my cardomain page.
But, it's a 2000 z28. It has a built transmission and FTi 3800 stall converter, lid, ported TB, Pacesetter LT's and y-pipe, dumped hooker muffler on a blowmaster catback, TB bypass, !air, !egr, msd plug wires and ngk tr55 plugs. It's got a few other things, but they are irrelevant to these issues
